[EDIT: when I wrote the text below the previous poster had only replied "juvenile cardinal?"--the reference to red-crested vs. yellow-billed had not yet been added, so I did not consider the latter.]
The last is a juvenile Red-crested Cardinal (formerly known as Brazilian Cardinal). An introduced bird of course.
Best,

Introduced, cardinal and juvenile, but the species involved is the Yellow-billed.
I know that Red-crested/Brazilian Cardinals have been present on Hawaii for many decades (first introduced in the 1930s). I wasn't aware that Yellow-billed had been introduced. If it has been introduced (which bkrownd's subsequently added remark suggests), then I agree it is a better fit since juvenile red-crested typically has a dark bill.

Yellow-billed are pretty common on some areas of the big island. I don't know about their overall distribution on other islands. I couldn't quickly find a photo of a juvenile yellow-billed to check if they have any hint of their black bib as juveniles or not. I also don't know about the range of bill and leg colors of juveniles of either species.

Chicks of both species are black-billed, but almost as soon as the Yellow-billed leaves the nest at least the lower mandible is largely dull orangish. In contrast, juv. Red-crested have an almost entirely black bill, with at most the cutting edge dull yellowish, though older immature often get the adult bill pattern & colour (pale greyish with a dark culmen) before having moulted fully into ad. plumage. Juveniles of both species have greyish legs. In addition to the colour of the bill, Red-crested appears proportionally heavier-billed than Yellow-billed, the section of the hood on the throat/chest usually appears paler than the section on the face-sides in juv. Yellow-billed (more uniform in juv. Red-crested), and Red-crested show a crest almost from the point they leave the nest, and while it is smaller than in the adults, it is virtually always relatively easy to see.
